Overloading Macro on Number of ArgumentsI have two macros FOO2 and FOO3: #define FOO2(x,y) ... #define FOO3(x,y,z) ... I want to define a new macro FOO as follows: #define FOO(x,y) FOO2(x,y) #define FOO(x,y,z) FOO3(x,y,z) But this doesn't work because macros do not overload on number of arguments. Without modifying FOO2 and FOO3, is there some way to define a macro FOO (using __VA_ARGS__ or otherwise) to get the same effect of dispatchi
